PATENT OSCAR F. PETERSEN, OF DES MOINES, IOWA.

SPECIFICATION forming part of Letters Patent No. 770,310, dated September 20, 1904.

Application filed May 28,1903. Serial No. 159,218. (No model.)

To a, whom it may concern.-

Be it known that I, OSCAR F. PETERSEN, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented anew and useful System for Heating, Cooling, Ventilating, and Lighting Buildings, of which the following is a specification.

My object is to reduce the labor and expense incident to establishing and operating means for heating, cooling, lighting, and ventilating buildings in towns and cities.

My invention consists in the construction, arrangement, and combination of two boilerfurnaces with a water-supply, pumps, a single smoke-stack, an oven in the smoke-stack, radiators in buildings, pipes for conveying steam, pipes for conveying water of condensation, an electric generator, and electric lights, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 is a diagrammatieal view that shows the positions of the different operative parts relative to each other and buildings on the opposite sides of streets in towns and cities as contemplated by my system for economically heating, lighting, and coolingbuildings. The conduit for inclosing the pipes for conveying heat is omitted from this plan view. Fig. 2 is a sectional view of the lower portion of a Smokestack and oven connected with a conduit for inclosing pipes for conveying steam and water and maintaining hot air in contact therewith. Fig. 3 is a transverse sectional view of the conduit and pipes inclosed therein. Fig. 4 is a detail view, partly in section, that shows the connection of the two boilers with a street-main pipe for conveying water.

The numerals l0 and 12 designate two boilerfurnaces. A stand-pipe 13 is connected therewith by means of tubes (0 for supplying water to the boiler. A filter 14, connected with a water-supply, has a pipe 15, extended to a pump 16, for elevating water into the standpipe.

The furnaces and 12 under the boilers connected therewith communicate with the smokestack 17 and an oven 18 in the bottom portion of the smoke-stack, as shown in Fig. 2. The even consists of a wall provided with transverse open-ended tubes 7) and a solid roof on its top. A conduit 19, preferably earthenware, extends from the base of the oven 18 a suitable distance of the main pipe 20, inclosed in the conduit, and at its end portion a ventilator in the form of a vertical branch 21 of the pipe and an electric rotary fan 22 are located therein for drawing heat from the oven 18 and forcing the exhaust out through apertures in the top of the branch 21. The conduit 19 is designed to extend and inclose the main and return pipes regardless of their lengths or directions. The two boilers are connected with a pump 23, as shown in Fig. 4, by pipes 2 1 and 25 and with the main distributing-pipes 20 by a branch 25%, in which is located a check-valve 27. 25, connected with the pump 2;), are provided with cut-oft valves 0 and the pipes 20 with cut-off valves 0'. The main pipes 20 are connected with the boilers and extend parallel with streets to be connected with radiators in buildings on opposite sides of the streets, as

The pipes 24C and indicated in Fig. 1, and return-pipes 26 are connected with the same radiators and the boilers. The two boilers are connected by a pipe (Z, that is provided with a cut-off valvef'. The return-pipes 26 and the main pipes 20 and a pipe 28 are to )e inclosed in conduits 19, as shown in Fig. 1).

Pipes 29 extend from the mains 20 to radiators in buildings and from thence to the return-pipes 26, as required, to convey water to the radiators and return water to the boilers.

To operate the pump 16 for elevating water into the stand-pipe 13 and the electric fan 22 and also to light buildings, a steam-engine 3 is connected with one of the boilers to operate a dynamo 31, that is electrically connected with the pump 16, the fan 22, and lights 32, located in buildings, as indicated in Fig. 1. After the boilers have been supplied with water and communication with the pump 23 established by opening the valves (2 in the pipes 2 1 and 25 the heat in the furnaces under the boilers supplements the force in the pump and will keep the hot water in circulation through the distributing-pipes 20, re-

To utilize the same apparatus for cooling buildings, I disconnect the two boilerfur.

naces by means of the cut-off valve f in the pipe (Z and use one of them for generating steam for operating the pump and circulating cold water through the boiler of the other furnace and the main pipes 20, pipes 29, and radiators connected therewith.

In the practical use of my invention, the conduit 19 being large enough to inclose the pipes 20 and 26, as shown in Fig. 3, products of combustion will enter the vacant space from the oven 18, communicating therewith, and the fan 22 will draw the products of combustion through the conduit 19, and in passing through the conduit the products of combustion in contact with the pipes 20 and 26 will aid in heating and keeping hot the water in said pipes. The exhaust occasioned through the apertures in the branch 21 occurs after the products of combustion have been greatly reduced in temperature and are discharged into the open air. The main purpose of the conduit 19, in combination with the furnace and the electric fan, is to draw from the oven and utilize the products of combustion to aid in heating water and keeping water hot in the pipes inclosed in the conduit 19. Water is fed to the boilers 10 and 12 at the same time through the pipes a, connected therewith. To discharge hot water from the two boilers at the same time into the main distributing-pipe 20, the valves 0 in the pipes 24 and 25 and the valves 0 in the pipes 20 are opened. The valve in the pipe 24, connected with the boiler 10, serves as a check-valve, and the valve in the pipe 25, connected with the boiler 12, as a combined check and cut-ofi' valve. To prevent forcing hot water in both directions relative to the pipe 252 and the two boilers, one of the check-valves 0 in the pipe 20 is kept closed. The valve 27 in the branch pipe 25% prevents any return of water that passed through it, and the steam-pressure from the boilers will aid in circulating the water through the system and return it to the boilers through the return-pipes 26. The steampressure supplemented by the action of the pump 23 will aid in circulating the water through the system and aid in returning it to the boilers through the pipes 26.

To force cold water from the boiler 10 through the distributing-pipe, radiators, and the return-pipes, the valve f in the connecting-pipe (Z between the boilers is closed and fire put under the boiler 12 only and that boiler disconnected from the distributing-pipe 20 by closing the valve 0 in the pipe that connects said boiler with the pump 23, as required to cut off communication between the boiler 12, the pump, and the main 20 and to pump cold water from the boiler 10. The power generated in the boiler 12 will then operate the pump 23, as required to circulate the cold water through the boiler 10, the distributingpipes 20, return-pipes 26, and branch pipes and radiators connected therewith.

The two boilers coact in forcing hot water to the radiators and also coact in forcing cold water to the radiators at the will of the operator.

Having thus described the purpose of my invention and the construction, function, and arrangement and combination of all the operative parts, the practical utility thereof will be obvious to persons familiar with the art to which it pertains.
